Solar Panels

Solar Panels for Installation Companies

As an installer, you need solar panels you can source quickly, price competitively, and specify with confidence. On sun.store, a professional B2B marketplace built for contractors, you compare offers from multiple suppliers side-by-side and see transparent stock and lead times at a glance. It’s a practical way to select solar panels for residential rooftops, commercial arrays, and utility projects without bouncing between spreadsheets and inboxes. Our catalog brings together hundreds of solar panels in standard and high-efficiency formats, so you can match budget, power class, frame color, and glass options to each job. You’ll find clear technical specification summaries, downloadable datasheets, and consistent naming so PV modules are easy to shortlist and present to clients. Whether you’re buying a few pallets or planning container-level procurement, the marketplace helps you track price, availability, and supplier terms in one place. Because sun.store is built for installers, the focus is on real-world decisions: which solar panels fit the rail layout, how the module format aligns with inverter strings, and how quickly you can get product on site. You can browse photovoltaic modules by brand, technology, or watt class, filter by certifications, and request custom quotes when you’re ready to lock in the order.

Solar Panel Types and Cell Technologies

Monocrystalline Panels

Most installers choose monocrystalline solar panels for high efficiency and a clean, uniform look. These modules are ideal where roof area is limited and every watt matters. Typical power classes span from the mid-400s W for standard residential frames up to 600 W+ in larger commercial formats. You’ll find full-black and black-frame options, standard 54-cell (approx.) formats for rooftops, and larger 72/78-cell (approx.) footprints for ground mount and flat roofs. Each listing includes a technical datasheet so you can review IV curves, temperature coefficients, and mechanical load ratings before you commit.

Bifacial Panels

Bifacial solar panels are designed to capture light from both the front and rear, delivering additional yield in the right conditions. They’re commonly used in ground-mount arrays, commercial flat roofs with reflective surfaces, carports, and canopies. Rear-side gain depends on site albedo, mounting height, and row spacing; we recommend reviewing the supplier’s guidance and your project simulations to estimate benefit. On sun.store, bifacial solar panels include notes on glass/backsheet or glass/glass construction, frame options, and mounting considerations so you can align design choices with racking and ballast plans.

TOPCon Technology

N-type TOPCon solar panels push efficiency higher while maintaining low degradation and stable performance across temperatures and low-light conditions. For installers, the practical upsides are compact arrays at a given power target, more headroom in string design, and reliable output across seasons. Many Tier 1 brands on sun.store offer TOPCon options, letting you pair advanced cell tech with known suppliers and straightforward warranty documentation.

Half-Cell Technology

Half-cell solar panels split full cells to reduce resistive losses and improve current handling. The result is higher real-world performance under partial shade and better resilience under mechanical stress. For installers, that means fewer callbacks related to mismatch or hot-spot risk and more flexibility when modules share roof space with vents, skylights, or parapets. You’ll find half-cell designs across monocrystalline, PERC, and N-type portfolios.

Solutions for Installation Professionals

sun.store is built to help you plan, price, and deliver solar panels with fewer surprises. You can place bulk orders with pallet or container pricing, send a request-a-quote for custom volumes, and coordinate delivery windows that match site schedules. The marketplace shows supplier lead times clearly, and you can message sellers to confirm packaging details, forklift needs, or offloading constraints. Comparison is at the core: shortlist solar panels from several suppliers, line up power class, cell technology, frame color, and warranty terms, then select the combination that fits your bill of materials. Because you also source inverters, optimizers, and racking, the catalog view helps you align module VOC/ISC with inverter input limits and verify clamp zones against rail profiles. Each product page includes a technical datasheet and certificates so your design package and O&M handover are complete.

Certifications and Quality Standards

IEC Certification

Solar panels listed on sun.store are supplied with documentation indicating compliance with relevant IEC standards (such as safety, performance, and durability). Always review the certificate references and report numbers in the product documents to confirm the exact standards and editions that apply to your chosen modules.

TÜV and Other Third-Party Testing

Many solar panels carry TÜV marks or equivalent third-party test indications, reflecting independent evaluation and, in some cases, factory audits. We recommend checking the datasheet and label images to verify the specific test house, mark usage, and any scope notes so your project file reflects accurate certification coverage.

Warranty Compliance

Most brands provide a separate product warranty alongside a longer performance warranty curve. Terms vary by manufacturer and region. On sun.store, each listing links to the warranty PDF and the supplier’s policy so you can confirm coverage periods, claim procedures, and any conditions tied to installation, cleaning, or environmental exposure. If you need clarification before purchase, use the marketplace messaging to request confirmation in writing from the seller.

Support and Resources for Installers

Every listing on sun.store provides transparent access to detailed product data sheets and certificates so you can vet solar panels quickly and keep your job files complete. While we don’t run a dedicated technical support or training program, our team is available to clarify features, confirm specification details, and help you compare options during selection. If you have compatibility questions—string sizing, clamp zones, mixed-string strategies—or need logistics planning for multi-site deliveries, reach out through the marketplace and we’ll help you get the right solar panels to the right place on time.
